T 0 all whom it may concern:

This invention relates to machines fori operating upon the projecting edges of the j soles of boots and shoes and is herein shown 5 embodied in a machine which is intended to burnish the stitch impressions that are commonly formed upon said edges. It will be understood however that certain features of the invention are not limited for use with a machine for burnishing stitch impresions but may be employed with advantage in machines for forming stitch impressions upon the edges of shoe soles or in machines which initially form the impressions and thereafter burnish the impressions so formed.

The primary object of .the present invention is to provide a machine of the above type which is adapted to produce work of a superior quality and which may be operated with a minimum amount of etfort on the part of the operator.

Another object of the invention is to improve generally the construction of machines of the above type. 'ith these objects in view a feature of the present invention consists in the provision in a machine for operating upon the edges of shoe soles of a non-rotatable tool havingan acting edge formed com lementary to the impresions to beform imparting an tool while its the work.

The present invention also contemplates the provision in a machine of this character of means for creating a holding pressure between the tool and the work and means for shifting said tool laterally to feed the work. Preferably there is provided means for relieving the holding pressure prior to the operating movement of the tooL a comgtrttively slight pressure being reserved eentheactmgedgeofthet and the or burnished and means for :perating movement to the ge 1s m engagement with 1 surface of the work during the finishing or Be it known that I. LOUIS G. Fnrx'r, i a subject of Great Britain, residing at Rochester. in the county of Monroe and i my present invention. State of Xew York. have invented certain new and useful Improvements in Machines 5 for Burnishing Stitch Impressions, of which the following is a specification, reference; being had therein to the accompanying 10 drawing.

polishing movement of the former.

The oregoing characteristic features of as also other novel features in -the construction and arrangement of l (parts of a practical machine made in acco ance with the invention, will be more fully understood from the detailed description hereinafter contained when read g in connection with the accompanying drawings forming part hereof and wherein a convenient embodiment of said invention is illustrated.

As will be duly appreciated the embodiment of the invention above noted which I have selected as a fitting disclosure of the invention, embraces a tool which notonly performs its desired function of finishing and burnishing the imitation stitch impressions but acts also to feed the work to carry the last burnished impresion away from operative relation with the tool. and to pre sent the next adjoining nnburnished impression mto position to be enga bv said tool, the movement of the too in this instance being first to descend under relatively heavy or maximum pressure into engagement with the unburm'shed impresion, thence laterally to feed the work a distance ual to the width of space intermediate a joining impresions. thence vertically to a comparatively slight extent to relieve the presure between the e im ression and the edge of the tool while at t same time maintaining surface en gement therebetween under relatively 'ght presnre, thence back and forth in a horizontal direction whereby to reciprocate in a line lengthwise of the impression.--and incidentally lengthwise of the edge of the tool.to polish of any rough of the impression or indentation as initially formed and to straighten and hnrnish the some, thence still farther vertically away from engagement with the work, and finally back in a reverse lateral direction to the starting point of its operation, that is. in a position to again descend into engagement with the next adommg impression.

In the drawings, Figure 1 is a perspective view of my machine, showing the same however as detached from its support or column; Fig. 2 is a side elevation, parts being broken away to better show some of the interior mechanism; Fig. 3 is a transverse section on the line .r-r of Fig 4;; Fig. 3' is a detail view of the cam plate; Fig. at is a top plan view, )arts being shown in section: Fig. 5 is a retail perspective view of the stationary crease gage for holdin" the work between the same and the tablea l igs. 1;. T and S are respectively a side elevation, an edge view. and a bottom view of the finishing burnishing and feeding tool; Fig. 9 is an elevation of a series of different iuterehaugeable tables; and Fig. 10 is :1 diagram illustrative of the various movements of the tool 'in a cycle of its operation.

Referring more specifically to the drawings. wherein like reference characters refer to tan-responding parts in the several news, A designates a base plate or frame upon which the moving parts of the mechamsm are mounted. said plate bein angular as shown to provide a downwar v extending flange a at one end thereof for supportin a tubular guide or casing C for the adjusta le shank D of a work table E. The bottom of this casing is open for the passage of an adjusting screw 0 for regulating the tension of its usual outwardly-thrustin spring J, a cable or link being connect to said shank and running to any convenient operating device such as a treadle (not shown), and a bolt F loosely engaging an ear on the shank of the table and threaded into the base plate A affording a means for limiting the outward movement thereof under the pressure of its spring. The work table just referred to is of the radially tapering or beveled disk type. but in the present instance contains additional merit in that the same has a rec& c in its lower surface adapted to removably receive a stub pintle e on the head of the shank D, the upper surface of said head being arranged at an incline so that the tapering surface of the table when in operating position thereon is approximately parallel with the lane of reciprocation of the tool H to be ereinafter further defined. The peripheral portion of the table at the point of greatest strain thereon, that is directly beneath the tool, is supported upon a large anti-friction roller d di at a right angle to the under surface of the table and in peripheral engagement therewith. The special manner of removably supporting the table upon its shank or support enables the provision of a series of interchangeable tables such as illustrated in Fig. 9, all of the tables a like portion formed complementary to and adapted to rotatably interfit with the support or shank. Rigidly mounted upon the base A is an angle bracket G having a vertical portion 9 and a right angle portion 9 arranged in substantially a horizontal lane and offset at its end to project forw y, said forwardly projecting pert-ion being bifurcated to form separated fingers g overhanging the work table to constitute a crease gage between which and the table the work is frictionally held owing to the upward pressure of the table under the influence of its spring.

,Arranged to work in the s ace intermediate the fingers g" is the finis ing and burnishing implement H, the same comprising a flat non r'otatable shank fixedly secured in a vieldable arm a of a holder I, and a single substantially horizontally disposed finishing and burnishing edge h of a shape complementary to the shape of the indentations to be treated. the only difl'erence between the shape of said indentations and said burnishing edge residing in the fact that the walls of the latter are disposed at a somewhat greater angle with respect to each other than the correspondin relation of the side walls or surfaces of the former, the purpose of this being to insure a suflicient surface contact between the burnishing edge of the tool and the side surfaces of the indentations while preventing any perceptible engagement of said edge with the base of the in dentations which would tend to deepen the indentations as initially formed, and which in many instances is not desirable.

The tool holder I is so mounted and operatively associated with the other parts of the working mechanism that the same may be given its desired vertical, lateral and reeiprccatory movements to accomplish the effect desired on the sole, as will presently appear.

J is an operating shaft mounted to rotate in suitable bearings formed in uprights J at opposite sides of the frame A, said shaft being adapted to be rotated through the medium of any convenient driving mechanism, that shown including a grooved wheel or pulley K for engagement by a belt in communication with any suitable source of war. to the shaft J is a cam plate havin a raised portion 1 on its riphery arrang to enga e a roller M carried by the tool holder I at the top thereof whereby the tool is in its initial or starting position ele vated to its highest position, or that indi cated as Starting position Fig. 10. The rotation of the shaft carries the raised portion of the cam just referred to away from the roller M of the tool holder and permits the holder and tool carried thereby to drop under the influence of a spring N arranged between the bottom face of the base A and an adjustable nut n on the lower end of a rod 1 passing loosely through an aperture in said base and connected at its upper end to the tool holder I, it being understood that the tool holder is pivoted at its rear end, as at o to the upper end of a pivoted bell crank lever 0 mounted on the base. the function of which latter will be soon pointed out, it be ing sufiic-ient to note at this oint that the second peripherally raised portion t on the opposite end of the bell crank ever carries a rod 0 under tension of another adjustable spring 0" similar to the one previously defined In connection with the holder. The up and down or vertical movement of the tool I 5 E t holder does not aifect the bell crank lever and its spring the latter during such move- 5 ment serving as a pivot only for the tool holder.

between the work table and the crease gage 1 and clamped therebetween prior to the dopressing of the implement as lastabove decam plate L engaging the overhanging or uppermost roller M on the tool hdlder to somewhat relieve the pressure of the tool on the surface of the indentation, it being noted that as soon as the cam t engages the holder, its spring X can no longer pull said holder and tool In a downward direction as before. This relieving of the ressure on the tool of course permits the tab e and work Of course the indented sole is interposed scribed, and when this is remembered it will be apparent that as the impression tool de- SCElll'lS it forcibly engages one of the indentattons of the sole, and owing to the comparatively greater strength of the spring X 5 the sole and work table are also depressed against the spring of the work table ta: free the work from engagement with the crease gage preparatory to the second movement of the tool which is to feed the work and which may now be followed. The rotation of the shaft continuing in the same direction as before carries the raised or thicker pon'ion of a side cam ring Q on the plate L away from a second roller P mounted upon a horizontal bracket on the tool holder,- which engagement as up to this stage of the operation held the tool and its holder from lateral movement,whereupon a horizontally disposed outwardly s rmg pressed rod R connected to the too holder and mounted to loosel play within an arm a on the nearest upri t J of the frame A will shift the tool holder and tool carried thereby laterally to the position marked "Third position (Fig. 10) which is for a distance equal to the desired length between adjoiningimpressions, and inasmuch as the tool remains in engagement with the impression enga ed by it in the first instance, the work is fed step by step with this lateral shifting of the tool to successively present the unburnished indentations in position to be burnished.

As soon as the implement reaches its third or burnishing position a peripherally corrugated portion S of the cam plate L comes into engagement with a third roller T near the pivotal point of the tool holder with the bell crank lever O and rapidly reciprocates the tool and holder in line with the burnishing edge of the tool, as also in line with the indentation being treated, to finish and burnish said indentation, the bell crank lever rocking on its pivot in short forward and reverse directions, alternately, and in rapid succession under the force of the corrugations just referred to and the spring 0". Previous to this burni a movement. however, the tool holder, an incidentally the tool; is elevated through the medium of a.

to raise sufiiciently to be again clamped between the table and crease gage.

F or the better class of work it 1s necessary to have a relatively slight degree of ressure between the burnishm edge an theis pivoted as at u to the rear portion of the main body of the holder I and arches over the 0 rating shaft, whence it extends forwar y to a pointnear the crease ga Said main body portion of the holder has a laterally extending lug or flange 11 through which loosely passes a screw U. the latter engaging at its inner end with the forward portion of the arm 1 and atits outer end carrying an adjustable nut u" interposed between which and the bottom of the lug is a relatively light sprin coiled upon the screw. Thus the arm I is constantly yieldably premed downwardly.

When the indentation is properly finished and burnished the raised portion I of the cam engages the roller 11 to elevate the tool holder and tool. and the cam ring Q again engages the roller Q to shift them laterally in a reverse direction back to the starting point, thereby completing a cycle of operation.

V is an adjustable stop having a threaded sleeve W engaging the arm r for regulating the tension of the laterally shifting spring R. Xuts Y, Z threaded on the rod R are arranged to abut the end of the sleeve W to limit the lateral movement of the holder and tool under the influence of the spring R.

'hen the work table E and work thereon is depressed away from the fingers g!" of the crease gage to permit the feeding movement of the work. it will be apparent that the relatively heavy spring X pulls the lever I bodily downward on its pivot 0. and the working edge of the burnishing tool H carried by the aun'liary lever i pivoted at it being resisted by the work with which said edge engages, the tendency of the downward movement of the lever I is to compress the light spring upon the rod U so that the spring X not only acts to draw downwardly the main lever I but also therewith the auxiliary lever which enablesi the depres ion of the work table and work against the action of the table supporting spring at as herein previously set forth.

It is to be understood that many changes and alterations may he made in the struc ture herein disclosed without departing from the spirit of the invention, and also that the invention is susceptible of other embodiments than that described.

The burnishing machine herein disclosed so far as the broader aspect of the invention is concerned. is covered by claims in my Patent No. 845.939. granted March 5, 1907. on a copending application. Serial No. 231.133. filed November 2. 190;. Therefore such claims are not included herein.
